the opposite side, and said part b extends into the cam-slot F on the rake for turning it up ot'La Fayette, in the county ot and down. This armed sleeve swings a little VState oflndana, have invented a new and Imfree ot' the bearing O, and it is connected to proved Harvester, of which the following` is a I the crankshaft G by the short arm H and conspecitieation My invention consists of the combination, with ascraper or rake pivoted to the rakestanda-rd to swing backward and forward to discharge the gavels, of a double cam on the rake-standard, in connection with the crank- To all whom it may concern Be it known that I, CHRISTOPHER LIDREN, 'Tippecanoe and just the sleeve E rightly to the bearing C. By the turning of the sleeve E a little free of the bearing O the part b is made to swing a little in the slot F, so that when it swings to the right it turns the rake up edgewise or vertically, as indicated in Fig. 4, to scrape on" the gavel, and when it swings the other way it turns the rake down, -as in Fig. 6, to swing it edgewise preparatory to going back to scrape oli' the gavel, and turn it down tlatwise prepara` tory to going forward again. It also consists ofthe platform contrived with a jointed section is carried by part et of the sleeve, which comes in contact with and sets the support O in Inoupper edge down, as in Fig. 6. At the front part of the platform is the jointed section K', which is raised by the rake coming to the upper side again, and t'alls back as soon as` the rake has passed it, closing the opening', so as to prevent any grain from falling through. At novel contrivanceof supporting and adjusting the same time that the rake comes up through levers for the reel, whereby it can be readily the platform its front edge runs up the staraised and lowered by the driver without movtionary cam L to be turned upright far enough ing from his seat, and Without altering the tenfor the part b of sleeve E to enter the grooves sion ofthe belt.

Figure l is a planview of my improved harvester. Fig. 2 is a top view of some ot' the parts and horizontal section ot' the rake-stand ard. Fig. 3 is a side elevation. transverse section on theline x a' of Fig. 1, and Figs. 5 and 6 are details of the rake or scraper. Similar letters ot' reference indicate correspondin g parts. Y

A is the rake or scraper, which is connected by its pivot B to the support O, which is The support O also has au arm, M, to communicate motion to the shaft N ofthe butt l guard or regulator N ofthe gavel by the connectingrod O. The'support P for the reelshat't is mounted on the standard Q, which slides freely along the lever R, on which it is mounted to shift the reel forward and backward, as requiredbythe diierent conditions ot' the grain, and the lever is pivoted at the end of its long arm to the standard of the shaft carrying the pulley S, which drives the reel, and is supported in a vertically-adjustable fulcrum for regulating the height ot' the reel, so that as the lever swings at or near the axis of wheel S, and the belt runs over idle-pulley T E is a sleeve, also mounted on the rake- I standard for swinging the rake, and also tor turning it on its own axis up and down. The arm wot' this sleeve bears against the support O, and enga-ges a cam on the end ofrake for shifting the reel along the lever or up and down. The adjusting-fulcrum consists of the 7 its tension is not affected essentially either by jointed standards U V and the adj nstin glever W. the latter bein g an elbow-lever permanently attached to the upper end of standard U, and said standard being pivoted to the top of the rake-standard, While standards V are pivoted .v to the top of standard U and to the lever, so

that by swinging lever W up and down the height, of the lever R will be varied. The lever W extends along the machine rearward near to the drivers seat, so that he can Work it while sitting to raise or lower the reel. The stud-pins X. on the lever Q hold lever W Wherever it is placed.

Having thus described my invention, I claimk as new and desire to secure by Letters Patent- 1. The combination of arm a, pivoted rake A B, and support C, as and for the purpose described. i

2. The combination ot' arm b on the lsleeve -E with thecam-groove F on the rake, arranged to turn on its axis at the same time that it swings forward and bac ward, and the sleeve E swings free or independent of the rake to some extent., substantially as specified.

3. The suspended or overhanging platform having a flexible front portion, in combination with a rake arranged to pass over it going back, and under it goin g forward, substantially as speciiied.

4. The combination of stationary cam L with the oscillating and swinging rake A, projection b, and the cam-groove F, substantially as specifled.

5. The combination, with lever R, `carrying adjustable reel and pulley T, of the pulley S,

as and for the purpose specified.
